Riesz potentials are convolution operators with fractional powers of some distance (Euclidean, Lorentz or other) to a point. From application point of view, such potentials are tools for solving differential equations of mathematical physics and inverse problems. For example, Marsel Riesz used these operators for writing the solution to the Cauchy problem for the wave equation and theory of the Radon transform is based on Riesz potentials. In this article, we use the Riesz potentials constructed with the help of generalized convolution for solution to the wave equations with Bessel operators. First, we describe general method of Riesz potentials, give basic definitions, introduce solvable equations and write suitable potentials (Riesz hyperbolic B-potentials). Then, we show that these potentials are absolutely convergent integrals for some functions and for some values of the parameter representing fractional powers of the Lorentz distance. Next we show the connection of the Riesz hyperbolic B-potentials with d’Alembert operators in which the Bessel operators are used in place of the second derivatives. Next we continue analytically considered potentials to the required parameter values that includes zero and show that when value of the parameter is zero these operators are identity operators. Finally, we solve singular initial value hyperbolic problems and give examples.

This article discusses criteria for comparing the effectiveness of energy resources. It focuses on the interrelationship between the effectiveness of energy resources and movement from one technological stage to another. What emerges is the consistent pattern of change in existing technologies, and increasingly evident is that, at their current stage of development, neither nano- nor biotechnology will lead to an evolution from the current and fifth technological stage to a sixth. Of note is that at present oil remains the key energy resource, which means that in the near future peak oil will force us to confront an unprecedented event in industrial history: energy degradation, which can be viewed as a regressive movement in the existing technological stage.

The Dst-index obtained by hourly average values of the magnetic field at four stations located in various longitudinal sectors at latitudes Φ′≈20-30° is the index of magnetic field depression at low latitudes during the magnetic storm periods. Recently for the characteristics of magnetic field depression the SYM-H index has been used. It is obtained from 1 min data of the magnetic field at ~10 stations, located mainly at latitudes Φ′≈40-50° [1]. It is considered in [2-4] that the SYM-H index is an analog of Dst but with a better temporal resolution. As shown in [5], during super magnetic storms with Dst variation ≥ 400 nT, the SYM-H variations can considerably differ from Dst behavior and thus the SYM-H index is not always an analog of Dst. In this paper the relation between the Dst and SYM-H variations for magnetic storms of different intensity, with Dst varying from ~ -50 nT to -450 nT is investigated.

Заглавие: Religion of Attila

Количество страниц: 220 с.

There are many literary works on Attila and Genghis Khan, written by European, American and Russian authors. One of their main shortcomings is the flagrant ignorance of the religion of these great historical figures. My works of Attila are devoted to the analysis of the great historical mysteries: - Relations between Attila and Aetius; - Enigmas of the Catalaunian Fields; - Mysteries of the meeting of Attila and Pope Leo in Italy. The form of literary works not only allows for the logical analysis of historical events, but also the creation of the psychological portraits of the participants in these events for a better understanding of the deep motivations of their actions.
Есть много литературных произведений об Аттиле и Чингисхане, написанных европейцами, американскими и российскими авторами. Один из их главных недостатков - вопиющее незнание религии этих великих исторических личностей. Мои работы про Аттилу, посвящены разбору великих исторических загадок: - Отношения Аттилы и Аэция; - Загадки каталаунских полей; - Тайны встречи Аттилы и Папы Льва в Италии. Форма литературных произведений позволяет не только логически анализировать исторические события, а также создать психологические портреты участников этих событий для лучшего понимания глубинной мотивации их действий.

We have gathered in this article the following sources: - the tangrist extracts from the inscriptions of the Turks of Siberia and Mongolia on the monuments erected in the 8th century on the banks of the Orkhon River (according to the book); - the testimonies of the authors and travelers of the XIII centuries on the religion of the Mongol Empire. These texts can serve as a solid basis for all reflections on classical Tangrism.
В этой статье мы собрали следующие источники: - тангристские отрывки из надписей тюрков Сибири и Монголии на памятниках, воздвигнутые в VIII веке на берегу реки Орхон ; - свидетельства авторов и путешественников XIII века о религии Монгольской империи. Эти тексты могут служить прочной основой для всех размышлений о классическом тангризме.

The Tangrian traditions are well preserved in Yakutia (Sakha Republic), we find their traces in Kazakhstan and in Central Asia, in South Siberia, in Turkey and in Mongolia.
Тангрийские традиции хорошо сохранились в Якутии (Республика Саха), мы находим их следы в Казахстане и Средней Азии, в Южной Сибири, в Турции и в Монголии.

Заглавие: Practice of Tangrism

Количество страниц: 10 с.

The various manifestations with the Tangrian prayers and the blessings of the participants remain a fundamental part of the contemporary Sakha (Yakut) culture. Focusing on large gatherings that are spectacular, such experiments operate more on the basis of emotional mobilization than on adherence to a religious and mythical content. Let us note the active participation in these events of representatives of other nations. Tangran events are also organized in Kazakhstan, Tatarstan, South Siberia and other countrys and regions.
Различные тангрийские молитвы и благословения остаются фундаментальной частью современной культуры саха (якутов). Они проводятся при больших и значительных событиях, такая практика основана больше на эмоциональной мобилизации, чем на приверженности религиозному и мифическому содержанию. Отметим активное участие в этих мероприятиях представителей других народов. Мероприятия Тангран также проводятся в Казахстане, Татарстане, Южной Сибири и других странах и регионах.
